Lineage

Available Endpoints

Get Lineage

Retrieve the lineage graph for an entity by ID or fully qualified name, with configurable upstream and downstream depth.

Create a lineage edge between two entities with optional column-level mappings, pipeline references, and SQL queries.

Remove a lineage edge between two entities.

Export the lineage graph for an entity as CSV.

Supported Entity Types

Lineage can be established between any entity types in OpenMetadata. Common combinations include:

From	To	Example
Table	Table	ETL transformations between source and target tables
Table	Dashboard	Dashboards consuming data from tables
Pipeline	Table	Pipelines producing data into tables
Topic	Table	Streaming data from Kafka topics into tables
Table	ML Model	Tables used as training data for ML models

Key Concepts

Edge: A directional lineage relationship from one entity to another

Column-level lineage: Mapping specific columns from a source entity to columns in a target entity

Pipeline reference: Associating a pipeline entity that powers the transformation

Upstream/Downstream depth: Controls how many hops to traverse when querying the lineage graph
